GATE.

SPECIFCATIN forming part of Letcers Patent No. 488,834, dated December27, 1892.

Application fi1ed June 30, 1892.

T0 aZZ whom it may conccrn:

Be it known that we, ROBERT W. REASONS and MARSHAL M. OZBIRN, citizens-of the United States of America, residing at Campbell, in the connty ofDunklin and State of Missouri, have invented certain new and usefn1Improvements in Gates; and we do hereby declare the following to be afull, c1ear, and exact description of the invention, sueh as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawing, and to letters ofreference marked thereon, which forms a part of this specification.

This invention relates to improvements in gates.

The object of the invention is to provide an expansible gate, whichwillbe opened on the approach of a vehicle by the axle of said vehiclestriking against a projecting arm on a crank-shaft, and closed byoperating a simi- 1ar crank shaft on the opposite side of the gate; saidcrank shafts being connected to turning posts which are connected to thesections of the gate; and the invention consists in the construction andcombination of the parts, as will be hereinafter fully set forth andparticularly pointed out in the claims.

The accompanying drawing, forming part of this specification: is aperspective view of a gate constructed in accordance with our invention.

A A designate parallel beams or sills to which are rigidly securednprights B B carrying the gate sections. To these uprights rare securedoutwardly projecting arms C 0 which form bearings for the upper ends oftnrning posts D D, the lower ends of which bear upon the sills, and eachturning post is provided with a cross-bar d and an arm d projecting atright angles to said cross-bar. Each npright B carries a short sectionof fence E to which near the lower end is pivoted a lever F, said leverbeing also pivoted to the central part of the gate section attached tothe upright.

The levers F F which are pivoted at their lower ends to the fencesections are also piv- -otally secnred to the gate sections to serve asSerial No. 438,625. (No modal.)

oted to each other on the principle of the lazy-tongs, so that they canbe operated to expand and contract. On the opposite side of each gaiesection from where thelevers F are pivoted is attached to the same pivota rodf, which is connected at its other end (0 the arm d which projectsfrom the turning post, so that when the tnrning post is operated ashereinafter described the sections will be opened or closed.

G G designate rods which are pivoted at their inner ends to thecross-bar d, the outer ends of said rods being provided With slots gthrough which pass the crank portions of the shaft H, said shaft beingpivoted between the silis A A and upon a cross-piece as shown. Eachcrank-shaft is provided centraily with an upwardly projecting arm hwhich inclines toward the gate when the sections are contracted to openthe gateway and in the opposite direction when the gateway is closed;these arms being of sufficient height to be operated by the ax1e of avehicle striking the same. It will be noted that by providing the s1otsin the ends of the rods G when a crank shaft is operated on one side ofthe gate the rods G G on the opposite side will s1ide npon the crankportions of the shaft and leave the arm h thereof in snbstantially anupright position.

In operation, when the gate is closed the projecting arms h of thecrank-shafts will be inclined away from the gate and toward anapproaching vehicle, and when the vehicle reaches one of the arms theaxle thereof will strike against said arm and rock the shaft toward thegate which will push npon the rods G G to turn the posts D D and drawnpon the gate sections throngh the connecting rods ff, so as to fold thegate sections and open the roadway. Af ter the vehicle passes throughand beyondthe gate it will operate the opposite arm h and crank shaft todraw upon the rods G G connected thereto and turn the posts D D toexpand the gate sections by pushing upon the connecting rods f f so asto close the gateway; the operation of each crank-shaft returning thearm h of the opposite cran]:- shaft t0 snbstantially a verticalposition.

Having thns described our invention we do not wish to be limited to theexact arrangement of the parts as shown in the drawing, as

the sills and uprights may be dispensed with and the operating partssupported in any suitable manner.

VVe claim:

1. In a gate, the eombination of the expansible sections pivoted tosupporting posts and to levers F F, the lower ends of said levers beingpivotally maintained in place; rods conmeeting the gate sections andlevers to crankarms ca1ried by turning posts,said posts also havingprojecting cross-bars d; and rods secured to said cross-bars andprovided With slotted ends which engage with crank-arms, substantiallyas showu, whereby when one of the crank-arms is rocked both sections ofthe gate Will be expanded or contracted.

2. In an expansible gate, the combiuation of the gate sections pivotedto supports or posts, rods or levers F pivoted at their upper ends tothe gate sections and at theiP 1ower ends to supports iocated betweenthe posts, turning posts D D having projecting arms, and rods connectingsaid arms to the gate sections and to rock shafts, substantiaily asshown, and for the purpose set forth.

3. In an expansible gate, the combination of agate section pivoted t0 asupportand provided on one side with a lever F which is pivoted theretoand to a support, a connecting rod fconneoting the gate section with anarm oarried by a turning post, a cross-bar (Z secured to the post, rodsG G pivoted to said cross-bar on opposite sides of the turning post andprovided with slotted ends, rock shafts having crank portions located insaid s1ots, and extensions 7L on said rock shafts, for the purpose setforth.

In testimony Where0f we affix out signatures in presence of twowitnesses.
